HAND-PRESS.

SPECIFICATION forming part o Letters Patent No. 369,990, dated September 13, 1887.

Application filed July 1, 1887. Serial No. 943,094. (No model.)

To all whom it may concern.'

Be it known that l, GEORGE W. KING, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hand-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in handpresses designed more especially for eX` traeting beef-juice, although well adapted to various other purposes, in which toggle-joints are compounded with the crank-movement, to the end that greatpressure may be had and the press quickly and easily operated. The cup in which the beef is pressed is connected with the toggle-joints, and the plunger is connected with a swinging frame or yoke, to the end that when the plunger and cup are separated the yoke and plunger may be swung back out of the way to give free access tothe cup. Ascrew and hand-wheel are provided to adjust the plunger endwise according to the thickness of material being pressed.

My invention also relates to the details of construction hereinafter described and claimed to the end that the press can be made at a small initial cost.

As a concentrated hydrogenous food and remedy in cases of fomentive dyspepsi a and in many 'eases of weakened digestion beef-juice has become famous, and is likely to retain its prestige. Heretofore beef-juice has usually been extracted by means of small hand screwpresses, that, so far as I know, are the only apparatus that the market affords for such purpose. I have therefore devised and reduced to practice the press illustrated in the accompanying drawings.

made of steel.

A A represent the side frames. These are usually made of cast-iron, and are rigidly connected by crossbars B, two of which latter are preferably integral with the longitudinal tiebar B to brace the frame-work. (See Fig. 3.) As a matter of economy the frame-work is fastened together by short stove-bolts a, countersunk holes having been cast in the side frames for the passage of these bolts. The respective ends of the cross-bars have lips b and b', for embracing the inside ribs of the side frames, the two lips being turned laterally to the right and left, (see Fig. 3,) so that the lower lip is entirely out from under the upper lip, by reason of which in molding a parting is had without setting a core. Vertical webs b2 connect the two lips just back of the ends of the latter. These webs abut the inside ribs of the side frames, and the webs are provided with slots b3, opening downward, so that each slot will leave its own core in the mold. The securing-bolts a pass through these slots, and the nuts a of the bolts are held in pockets b", cast in the cross-bar next inside the webs, the said pockets opening downward, so that they also leave their own cores in the sand in molding, all of which will be readily understood by molders. The side frames have heavy parts A', the latter having holes cast therein for receiving, respectively, the trunnions O2 of the yoke C and for re ceiving the trunnions DZ of the lower arms of the toggle-joints. The upper ends ofthe side frames have holes feast in77 for receiving the ends E of the crank-shaft E. The lower arms, D, of the togglejoints are alike, and consist of rollers D', the latter terminating in trunnions D2 aforesaid, together with webs d, ribs d', and ears d2, all cast integral. The ears d2 are arranged in pairs to embrace depending ears f of the upper arms, F, of' the togglejoints, all of these ears being cored laterally to receive the pintles H, the latter for small presses being usually about a half-inch in diameter and The arms F terminate above in rollers F', that are seated in corresponding grooves, g, made in the under surface of cup G. A small bolt, g3, cast in, depends from the bottom of the cup for securing the cap G. The latter fits the under side of rollers F and fills laterally the space f', so that the afore- IOO said cap and bolt hold both arms F in place vertically and laterally.

The crank-shaft E has arms FP and E, extending in opposite directions to serve as cranks, and these arms have, respectively, wrists e and e', arranged as shown in Fig. 4. A thimble, E4, is set slightly oblique from perpendicular to the shaft, but is preferably in the same plane Vwith the cranks, the cranks, shaft, and thimble being cast integral. Thimble E* is made to receive the wooden lever I, the latter terminating in handles i and i/,wood being preferable for this purpose, as it is more agreeable to lhandle than metal. The sleeve and lever are omitted from Fig. 1, so as not to obscure the cranks and links. The Obliquity of the thimble brings the handle 11 outside of the yoke C when the lever I is reversed. Links J and J connect with the wrists e and e and with the respective pintles H. Link J is curved downward at the ends, as shown in Fig. 1, so as to extend over the rear pintle, and so as to engage the top of the crank-shaft when the parts are in the position shown in solid lines, Fig. 1, such engagement of the link with the crank-shaft forming a stop for the cranks when the latter reach the dead-center line. The shorter link, J', trends upward, as shown,and when the cranks are reversed link J, by engaging the under side o'f the crankshaft, stops the crank on the other deadcenter. Wrists e` and e have lugs e or teats nextl the free ends thereof, and the links have annular recesses j ony the inner face thereof for the lugs eto operate in, by which arrangement the innerV faces of the links are brought about flush withthe free ends of the wrist, and consequently the two links can be made to opcrateV side by side and close together, it being desirable to attach the links to the toggle-j oint as near as possible to the center of the pintles H. Grooves j of the links span` the lugs e? in assembling the linksonthe wrist.

It will be observed thatin the position shown in Figs. 1 and 4t the one lug e? extends above wrist e', while the lug on wrist e extends be,-

low the latter, and that the groove j of link Jis on the rearward side of hole J2, (see Fig. 5,) While with link J the groove j is o n the forward side of hole J 2. The grooves j aretheref ore on the opposite sides of holes J2 from where the wrists press hard in operating the machine; also, in placing thel links upon the wrist the links have to be turned rearward to cause grooves j to register with lugs e2, and when the links are in position on the wrists and turned forward to couple with the togglejoints the said grooves 'and lugs are brought into such relative position that they never pass each other in operating the press; otherwise a groove and lug might interlock and cause a breakdown. l

In Fig. 2 it will be observed that the web d of the lower arm of the front togglejoint is notched at d3 to receive the forward end of link J, by which arrangement thelink is held in place endwise of the pintle H. The lower arm of the rear toggle-joint is reversed, and consequently the notch d3 is brought in position to receive the forward end of link J.

The cup G has a discharging-spout,g,the latter having notches g2, for holding the bail of a suitable container for receiving liquid extract. Yoke C has at the bottom a roller, C', connecting the side arms of the yoke, the roller terminating in the aforesaid trunnions C2. Above, the yoke has a hollow cylindrical head, c, with internal screw-threads, c', cast in. These screwthreads engage external screwthreads, L', made on the body of the plunger L. The plunger is cast hollow, as shown in Fig. 1, to save metal. The head of the plunger L2 fits loosely in cup G. An upwardlyprojecting hub, Z, receives the bolt O, the latter being cast in.

K is aV hand-wheel for operating t-he plunger, notches Z being cast in the upper edge of the plunger to receive the spokes ofthe handwheel, the securing-bolt O passing through a suitable hole made at the center of the hub of the wheel. A follower, M, fits loosely outside the plunger above head L?. When the cup G is depressed, the follower is left suspended on head L2. When cup G is elevated, the follower rests on the rim ofthe cup and prevents the juice from squirting out between the rim of the cup yand the head of the plunger.

In operating the press the plunger is screwed up or down, according tothe thickness of meat or other material to be pressed. With the handle i turned forward the toggle-j oints are turned outward in thepositi'on shown in dot- IOC ted lines, Fig. 1, thereby depressing cup G be- -low the line of the vplunger-head, after which the yoke is canted rearward, leaving the cup G unobstructed. Lugs ls and s are cast on the inner faces of the side frames toV stop the yoke in its upright or in its inclined po,- sition. After, the material to be pressed is laid in the cup G the yoke is turned forward to bring the plunger over the cup, after which the lever I is reversed-.that is, turned over rearward. The arms of the respective toggle-joints are brought in line simultaneously with the cranks reaching their dead-centers, whereby a very great pressure may be had between the plunger-head and cup bottom, such pressure being ample for all practical purposes,andis had by applying a few pounds pressure to the handle i. With the parts working freely a finger of the operator. is sufficient to turn the lever I rearward until theplungerhead is brought to bear on the material in the cup, and this should occur withthe lever I inclining rearward approximately at an angle of forty-'five degrees to the deadcenter line of the cranks. From thence the operator presses down on the handle z', and if it is found that the lever I cannot be brought dow'n toa horizontal position with moderate force applied thereto the operator raises the lever slightly, and bymeans of the hand-wheel backsup the plunger a trifle, and then brings the lever I down to its horizontal position. If, on the other hand, too little pressure has accrued, the handle t' is raised and the plunger is screwed down perhaps an eighth or quarter turn, more or less, as may be required, after which the operator again brings the lever to its horizontal position. The operator having one hand on the lever and the other hand on the hand-wheel,these manipulations are made in a moment. Vhen the handle i is turned forward,the handle t" is in position for raising the rear end of the press,after which the press is easily moved about on the rollers l?. Vith the arrangement of toggle joints and mechanism for operating the saine, the cup G is moved in a vertical line without other guidance than it receives from the toggle-joints. The material for the press may be nearly all of castiron,'and no fitting is required except to drill the small holes for the axial pins of the rollers I). The press can therefore be made at a small initial cost.

In carrying out my invention various modifications may be had in the mechanical coustruction without departing from the spirit and purpose of my invention. For instance, about every member of the press could vary more or less in form and still be made to answer the purpose. Vhat in Figs. l and 2 is shown as cup G might be castin two sections, the division being on the line yy. Fig. 8, if such construction were preferred. This would admit of the cup proper being removed in case the press were wanted for such purposes as would not require a cup.
